getConcurrencyModelExecutorService

public final java.util.concurrent.ExecutorService getConcurrencyModelExecutorService(SipContext sipContext,

This method return an ExecutorService depending on the current concurrency strategy. It can return the executor of a sip session, app session or just threadpool executor which doesn't limit concurrent processing of requests per app or sip session. Since 0.8.1 it always return threadpool executor which doesn't limit concurrent processing since concurrency is achieved through semaphore

Parameters:

sipServletMessage - the request you put here must have app and sip session associated

Returns:
